Application filed May le,

To all 'whom t may conce/rn:

Be it known that l. Emmer @nessunnacnna. a citizen of the United States, and resident ot' Fajardo, -liDorto ltico7 have invented certain new andy useful improvements in Automatic Regulators7 of which the following is a specication.

My invention relates to regulators and has tor its object to provide a simple and etlicient apparatus whereby the admixture of certain predetermined media may be automatically controlled and whereby the proportions ot the admixture may be automatically maintained at a relatively constant point. A i'urther object ot' my invention is to construct the regulator in such a manner that it may be readily adjusted to automatically provide any variety oit admixtures which may be desired. rlhe invention will be fully described hereinafter and the teatures of novelty will be pointed out in the appended claims.

'lt will be understood that the regulator may be usrd for controlling the admixture ot a plurality ot gaseous media, a plurality ot liquid` media gaseous and liquid media, liquelied solids with any other medium, gasitied liquids with any other medium, liqueiied e ses with any other medium and in short may be utilized in connection with the admixture ot any number of media in the predetermined proportion regardless ot they quantity or volume. rlhus in practice the apparatus is, tor instance, adaptable to the admixture ot paints or chemicals or for maintainingthe correct mixture of the welding gas in Oxy-acetylene welding apparatus or it may be utilized in connection with oil burning furnaces. For the purposes of illustration and description and without intending to define the limits of the invention, the latter is shown, in the accompanying drawings7 as used in connection with an oil burner; in said drawings Fig. l is a sectional elevation; Fig. 2 is a side elevation; 3 is a horizontal section on the line 3 3 or" l and Figs. d and 5 are detail vie is showing` another form of my invention.

ln the form illustrated in the drawings the regulator comprises a body l0 which is provided with transverse passages il and l2 communicating at opposite ends respectively with internally screwthreaded re-v LQBO. Serial No. 381,504.

ccssrs 13 and lli and l5 and 16. The recesses i3 and l5 constitute inlets and are adapted to accommodate pipes 17 and lf3 whefeby said passages ll and i2 are connected respectively with 'a source ot liquid tool, such as oil, and with a source ot atomizin medium such as steam, air or under pressure. rllhe recesses le and 16 on the other hand constitute outlets and are inn tended to receive the ends ot pipes 19 and aeotiv/.ly whereby the passages ll and connected with the atomizing device ch in the illustrated example may be an oil burner ot any conventional type and which has not been illustrated it forms no cart oit the present invention. The passages ll and 12 areintersected by valve channels 2l and 22 respectively in which the vaives 23 and 247 whereby communication between the inlet pipes 17 and i8 and the respective outlet pipes i9 and 20 is con trolled. are movable and adjustable.

lt will be understood that the passages il and l2 and the valves 23 and 24 are specially cut or in other words are designed and dimeosioned in a predetermined manner with respect to each other and in accordance with the particular purpose for which the regulator. in each case, is intended.

l rlFhus in the iliustrated example, the passages ll and l2 are cylindrical and ot predetermined area while the valves 23 and 2li are if the term ot cylindrical plunger-s having d imeters corresponding to those oli' the pasll and l2 and having their tree ends cut at angles ot approximately 4:50 as shown in l. its shown in the drawings the valves 2.3 and are carried by a yolre 25 so as to be adjustable relatively thereto in the direction ot their length and also about their axes. suitable loch nuts 26 being provided tor securing said valves in their adjusted positions; stuffing boxes 27 ot appro- 'viate construction may be provided tor .ling the joints between said valves and the valve body.

.any suit-able means may be provided tor concurrently operatingsaid valves 23 and 24;. the illustrated example including two means, one intended t'or manual operation and the other for automatic operation. rThe automatic means may comprise a piston, a diaphragm or other mrchanical or elec trical device and in the present instance is shown in the form of a piston 28 connected by means of a rod 29 with the yolre 25 and slidable in a cylinder 30. The latter may be mounted uponmembers 3l suitably securedito the valve body l0 as by nuts 82 and is connected by means oi? a pipe 38 with the boiler in which steam vis `being generated, the Connection being such that thepiston is influenced by the steam pressure in said boiler. A spring 3e is located between the yoke and a plug Bewhich is screwed into the body l0 and serves to counteract or re sist the action oit the piston 28 or equivalent device. the tension or said spring 84E being changed by adjusting the plug 85 in the body l0. ln its illustrated tormthe `regulater includes also a means whereby the ymovement or the valves 28 and 24: in the direction off opening is arrested or in other words whereby the :tully open position of said valves is' positively determined.` shown, `this means which, in addition to its yother functions, constitutes the manually op* erated means previously mentioned, comprises a limit rod 86 which is attached to the yoke 25 and which extends through and beyond an axial opening 87 in the plug 85, it beingunderstood that the dimensions of said opening 87 are such as toy permit a sliding movement of the rod l86 relatively to said plug 35. The rod 86 is screwthreaded for the Ireception o't a hand wheel 38 and a limit nut' 39, the former being arranged for contact with the plug 35 and the nut 89 being set to a-predetermined posi` tion to-prevent over-woilringof the apparatus; that is to say, to prevent more than a pidetermi1ied maximum of oil and steam from passing through the regulator for a boiler ot given Capacity.

When constructed in the form so far described the regulator isvadjusted and operates as follows: 'p

rlhe connections between the body 10 and the fuel pipe 1.7 and steam pipe 18 and between the outlets lll and 16 and the burner having been made, the cylinder 30, above the piston 28 is filled with water and vconnected by means oi the pipe 83 with 'the boiler.

Either at this stage or previously the valves 23 and 24 are adjusted relatively to each other in accordance with'the mixture desired, it being understood that the adjustment may require a lengthwise movement of one or both valves ora rotative movement aboutftheir axes or both a lengthwise and rotative adjustment of one or both valves to secure the vdesired result. f

Steam is now opened up under full pressure and also opened up to the burner7 the valves 23 and '24 kat this stage however, being in their closed position. -When this has been done rthe spring plug 35 is slowly taken up oradjusted until steam isy seen to escape from the burner, the adjustment olf'.

said plug serving to open up the valves 23 and 24. The v-oil connection between the regulator and the burner which up to this point has remained closed, is -now opened and the burner is ignitedyin the customary manner. fis-soon as the boiler pressure appears to drop, the spring plug 85 is adjusted inwardly still further t0 open up the valves 23 and 24 to a greater extent,

which vadjustment is continued until. the

boiler pressure remains constant. 1When this condition has been reached the yhand wheel,

38 is adjusted on the limit rod 86 untilthere is a clearance of about one-sixteenth of `an inchbetween it and the plug 35 alter which the limit nut 89 is loosely set against said hand wheel.. The regulator is now properly rmixture for an increased flame. ll`hit1s,vwhat ever adjustment of the valves 28 and 24 may follow from an actuation of thepiston 28 or because of the action oi' the spring- 84E, the correct proportions of oil 'and steam required in each instanceto secure maximum eihciency' are automatically maintained while 'at the same time the boiler pressure is maintained at a substantially constant point without the services oit anattendant.

When it is desired to shut down the boiler, the hand wheel 88 is screwed up on the limit rod 36 and by bearing against the plug closes the valves and 24 andA thus extinguishes the burner; when starting` up, thehand wheel 38 is operatedin the reverse direction, after the main steam and oil valves have been opened u pI respectively. The hand wheel 88 in (fo-operation with the plug also serves Ito limit the extent of opening of the valves 28 and 24; under the action ot the spring 84 when pressure on the piston 28 is reduced; by adjusting the position oi' said hand wheel on the limit rod 36 the extent oi opening of saidv valves 28 and 2a may be varied. l i

y By rotating said valves 28 and 24 about theiraxes and setting themD the supply oi media passing beyond said valves'may be regulated so as toprovideany desired rela tive proportions 'in the mixture, and the proper mixture, once obtained, will be maintained regardless of the positions which said valves fmay assume. ln the casev of oil burners this lmeans that perfect combustion is obtained and no surplus steam, air, oil or gas will be blown into the furnace.

ln the form shown in Figs, l and 5 the valves L13 and Qfl are connected, by means of stems 23a and 2li;a with plungers 23h and 2lb, each located in axial alignment with the respective valves and slidably mounted in stuiiing boXes 27a. T his arrangement provides a balanced construction in which the oil pressure and the steam pressure is etiiect-ive respectively upon the plungers 231 and 245 and counteracts the eiiect oit such pressure upony the end taces oit the valves and 24, which being in the same direction as the tension exerted by the spring 34, might effect the automatic action ot said valves and thereby unintentionally bring about an operation of the regulator out ont harmony with its adjustment. With this balanced arrangement nothing affects the operation of the valves 23 and 2a other than the boiler pressure exerted upon the piston Q8 and the action oit the spring 311-. Otherwise this torm ot construction be the saine and operate in the same way as iirst described.

The device is simple in' construction and ecient in operation and may be utilized in any case where an adminture ot media in predetermined proportions is desired to be delivered and `maintained at a given point.

Various changes in the forms shown and described may be made within the scope of the claims without departing from the spirit ot my invention.
